Roscommon Conservation Airport

Roscommon Conservation Airport has two runways. Runway 10/28 measures 3552 x 75 ft (1083 x 23 m) and is paved with asphalt. Runway 18/36 measures 2500 x 100 ft (762 x 30 m) and is turf.[1][2]

In 2020, work began at the airport to renovate runway 10/28. Though delayed due to the COVID-19 pandemic, work at the airport was completed in 2021. Work was done to adjust paving cross sections and grading; in particular, the width of the concrete supporting the runway was doubled.[5]

For the 12-month period ending December 31, 2018, the airport averages 504 aircraft operations per year, an average of 42 per month. It is all general aviation. For the same time period, 3 aircraft are based at the airport, all airplanes: 2 single-engine and 1 multi-engine.[1][2]

There is no fixed-base operator at the airport, and no fuel is available.[6][7]

• On May 20, 2001, a Cessna 152 collided with trees after an aborted takeoff from Roscommon Conservation Airport. The pilot reported that the takeoff roll was longer than expected, likely due to heavy loading, the rough runway surface, and a relatively high density altitude. The aircraft lifted off on time, but during climbout, the pilot "sensed a lack of acceleration and climb performance," so he lowered the nose to gain airspeed. The pilot subsequently pitched for based angle of climb airspeed, but the aircraft still would not climb, and it became evident that it would not clear the trees ahead. The pilot therefore decided to settle back to the airport and risk damaging the aircraft instead of likely serious bodily harm. The probable cause of the accident was found to be the pilot's failure to maintain clearance from the trees, with factors including a tailwind, high weight and density altitude, the rough runway, and the pilot's failure to calculate takeoff performance.[8][9]
